Abstract (en)
A drive line (26) for an implement (14) attachable to a tractor (10) includes two double cross bearing universal joints (32 and 34). During turns between passes over crop the power delivered by the line must turn through a working angle as large as 90 DEG . but for such a tight turn each joint turns the power through two angles of only 22 1/2 DEG thus enabing full power to be used between passes without undue wear. The implement (14) is attached to lower links (18) of the tractor (10) by way of a yoke (16) which in turn is connected to a drawbar (12) of the implement (14) via a pair of channel-shaped supports (20, 22) rigid with, and at right angles to, one another. One support (20) receives the forward end of the drawbar (12) in its channel and is connected thereto by a vertical pivot pin (21). The other support (22) similarly receives the yoke (16) to which it is connected by a horizontal pivot pin (23). There is thus provided a drive and an arrangement for attaching the implement (14) to the tractor (10) which permits tight turns to be made efficiently.
